REEL FOR CORN-HARVESTERS.

SPECIFICATION forming part of Letters Patent No. 435,238, dated August 26, 1890. Application tiled December 23, 1889. Serial No. 334,625. (No model.)

To all whom it may concern: v v

Be it known that we, IRvIN MoCoLLrsTEE and BENJAMIN F. RENNERD, of Chillicothe, in the county of Ross, State of Ohio, have invented certain new and useful Improvements in Corn-Harvesters, of which the following is a specification, reference being had to the accompanying drawings.

The object of our invention is to produce a cheap and comparatively simple machine for harvesting corn, and one which is adapted to take up the stalks that have been thrown down, so that none of the work has to be done by hand.

In the accompanying drawings, Figure l is a top plan view of our machine with one of the side wheels broken away. Fig. 2 is a vertical section along the line y of Fig. 1.

Referring t-o letters on the drawings, A indicates the driving-wheel of the machine. It is carried upon one side of the frame A of the machine. The frame is supported by another wheel upon its opposite side; but this wheel, being of ordinary construction and being in no manner related to our invention, is not shown in the drawings.

To the axle of the wheel A is secured a combined sprocket and bevel geared wheel B. The sprocket-wheel B, by means of the sprocket-band C, communicates motion through the sprocket-wheel C to the shaft E.

Secured to t-he shaftE are two bevel-wheels E', that communicate motion from the shaft E through each of the bevel-wheels F to the vertical shafts F. Upon the head of each of 'these shafts is secured a sprocket-wheel G, around which passes the sprocket-band H. G indicate guide wheels for each of the bands H. These wheels are borne upon frames J, that are inwardly and outwardly and longitudinally adjustable -by means of nuts and bolts working in the slots K and L, respectively.

M indicates the frames upon which are borne the frames J. By means of the inward and outward adj ust-ment of the frames J upon the frames M the distance between the bands H may be varied at will.

T indicates projections borne at short intervals upon the bands H. By means of said projections the stalks of corn, as the machine is drawn along a row, (represented by the line y,) are caught and carried against the knives S, which sever them from the ground. The stalks after they are severed from the ground are borne backward by the band H between the guides Q until they drop clear of the machine.

The longitudinal adjustment of the frames J upon the frame M aifords means for regulating the relative positions of the diiferent parts carried by the frames J.

The knives S (illustrated in the drawings) are of the ordinary reciprocating kind, and are driven by the bevel-gear` B through the spur-gear V, shaft D, and crank V. Any suitable form of mechanism may be employed for operating the knives S.

Upon the shaft-s F, below the sprocketwheels G, are secured beveled gear-wheels WV, that mesh with a bevel-gear upon the shaft of the sprocket-wheels U, that drive the band O.

O indicates guide-wheels borne upon the frames J, and O2 corresponding guide-wheels .borne upon the projecting arm N of the frame M. Each of the' bands O passes around one of the wheels U, O', and O2, in the manner illustrated in the drawings.

O3 indicates bracket-arms adj ustably borne on the frames J, whereby the wheels O may be adjusted to suit the adjustment of the frames J. If it were not for the adj ustability of these arms a change of position of the frames J would interfere with the operation of the band O; but by the aid of them this difflculty is avoided.

P indicates projections upon the bands O, which catch and pick up fallen stalks that lie in the way of the machine. After they have been caught by the projections P the stalks are lifted up the incline of the band O until they reach the band H, when they have attained an upright position, and are then in proper relation to the knives to be out by them.

What we claim is In a corn-harvester, the combination, with the main frame of the machine and frames to suit the adjustment of the bands H, sub- M borne thereon, of the frames J, adj ustaobly stantially as set forth. borne upon the frames M, the sprocket-bands H, operatively carried upon the frames J, the (LIIBS`ITERD 5 bands O, and wheels 02, U, and O', the wheels O' being carried upon the frames J by means WVitnesses: of the adjustable bracketfarms O3, whereby FREDRICK KIRSCH, the tension of the bands O maybe regulated EBENEZER K.
